Plan an upgrade¶
A database upgrade must be planned and tested. The downtime requirements are a major factor in the upgrade strategy.
The following steps should be reviewed and tested:
|Review current environment
|Research which server components/plugins are used, application versions are used, user connections and when is the database has the heaviest traffic.
|Hardware and software requirements
|Review if any infrastructure upgrades are required to support the database upgrade. Consider if the hardware and the software must be upgraded.
|Do regression testing
|Perform regression testing in the test environment.
|Review the high priority processes to plan testing the process.
|Back up and rollback
|Plan what happens if the upgrade fails. Back up the important files, including configuration files. Be aware that after the database server is upgraded, downgrading is not supported.
|Review the release notes for the new version.
